RICE-HULLING MACHINE.

SPECIFICATION forming' part 0f Letters Patent NO. 409,905, dated. August 27, 1889.

Application filed January Z2, 1889. Serial No. 297,173. (No model.)

To @ZZ whom it may concern:

Be it kn own that I, ARTHUR A. BOURGEOIS, of Ariel, in the parish of La Fourche and State of Louisiana, have invented a new and Improved Rice-IIulling Machine, of which the following is a full, clear, and exact descrip tion.

The object of my invent-ion is to provide a simple, cheap, and durable rice-hulling machine; and to the end named the invention consists of the peculiar construction and arrangement of parts, as will be hereinafter fully described, and specifically pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this Specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure lis aface view of my improved ricehulling machine. Fig. 2 isa cross-sectional View thereof, the view being taken on line Qc of Fig. l. Fig. 3 is a perspective view of the movable plate, and Fig. 4. is a perspective view of a modified form of plate.

In constructing the machine forming the Subject-matter of this application I provide a bedeplate l0, having transverse ribs ll, the upper faces of said ribsbeing inclined,as shown at a. To the sides of this bed-plate l0, I bolt side plates l2, that are formed with lugs or ears 13, adapted to receive adjusting-screws 14, as many of these lugs or ears being provided as may be deemed necessary or advisable. Above the ribbed or roughened portion of the plate l0 there is an inclined section b, as shown best in Fig. 2. l

In advance of the plate l0, I mount a plate 20, having ribs 2l,the upper faces of said ribs being inclined, as shown at c, and to this plate 2O there is pivotally connected a pitman 22, which extends to a crank-shaft 23, that is mounted in bearings formed at the lower ends of the side plates l2. Upon one end of the shaft 23, I mount a balance-wheel 25, and

upon the opposite end thereof a crank arm or handle 26. The upper end of the plate 20 extending arm 27, which enters a hopper 30, said hopper being provided with a slide 3l, which may be inoved so that any desired quantity of grain will be delivered from theA hopper.

In operation a rotary motion is imparted to the shaft 23, which motion of the shaft will cause the reciprocation of the plate 20, and as the plate 20 is reciprocated the unhulled rice is allowed to drop from the hopper 30 into the space between the two plates lO and 20, a proper feeding of the rice being secured bythe agitator 27. To adjust the plate 20, the screws 14 are moved so as to carry thc plate toward the plate l0, the position of the screws defining the space between the two plates, as will be readily understood.

In certain cases it might be desirable to dispense with the crank-shaft and to reciprecate the plate 2O by hand 5 and to this end I would at times provide such plate with a handle, such as the one shown at 32 in Fig. il. In practice I would make the mills so that all parts could be duplicated.

Ilavin g thus described my invention, I claim as new and desire to secure by Letters Pat ent- The combination, with a corrugated plate l0, formed with an inclined face of a corrugated-faced plate 20, formed with an inclined section d, an agitator extending upward from the plate 20, a hopper that is entered by the agitator, a slide or trap arranged in connection with the hopper, a crank-shaft, and connections between the crank-shaft and the plate 20, substantially as described.

ARTHUR A. BoURGEois.
